SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Example
1. Add the virtual disk to the system configuration database and associate it with a storage pool:
->
ADD DISK $VDISK00, SENDTO STORAGE, ANTLOCATION $SYSTEM, &
-> POOL $POOL01, PENDOPSLOCATION $SYSTEM, TYPE VIRTUAL
2. Verify the attributes recorded in the system configuration database:
-> INFO DISK $VDISK00
3. See “Starting a Virtual Disk” (page 150).
Example: Adding a Similar Disk Using the LIKE Attribute
To add another disk similar to an existing disk on the same system, you can use the LIKE attribute.
If the disk is an internal disk, specify a unique name and the group and slot number:
-> ADD DISK $VDISK02, SENDTO STORAGE, LIKE $VDISK00, &
-> TYPE VIRTUAL, ANTLOCATION $DATA00, PENDOPSLOCATION $DATA00
Example Adding a Similar Disk Using the OBEYFORM Attribute
To configure the same or a similar disk on another system, create a command file by using the
OBEYFORM attribute of the INFO DISK command. You can copy this file to another system or add
it to a different configuration file on the current system.
1. Capture the configuration for an existing virtual disk:
-> INFO / OUT LOG / $TECH, OBEYFORM
== STORAGE - Detailed Info Virtual DISK in obeyform: \COMM.$TECH
ADD DISK $TECH , &
SENDTO STORAGE , &
TYPE VIRTUAL , &
ANTCAPACITY 1000000 , &
ANTLOCATION $P6D01.ZYS00000.A0000QBC, &
BACKUPCPU 8 , &
CACHESIZE 30000 , &
HIGHPIN OFF, &
MODE QUIET, &
PENDOPSLOCATION $P6D01.ZYS00000.A0000QBD, &
POOL $POOL6, &
PRIMARYCPU 9 , &
PROGRAM $SYSTEM.SYSTEM.OVDP, &
STARTSTATE STARTED
2. Optionally edit the resulting log file to:
• Specify a unique disk name
• Remove the subvolume and file name from ANTLOCATION and PENDOPSLOCATION
3. Enter the log file contents either by copying and pasting into an SCF command line or by
using the log file as a command file.
Troubleshooting Problems With Adding a Virtual Disk
1. Use an INFO or STATUS command to detect problems when adding a virtual disk:
• The INFO command displays a process that has a configuration record but the
Configuration State is “No Definition With SMF master process.”
• The STATUS command also displays the Configuration State “No Definition With SMF
master process.”
2. Check the EMS event messages for the storage subsystem.
